Appropriate Filtering and Monitoring: What’s New for 2026?

Following the public consultation and publication of updated guidance from the UK Safer Internet Centre, the 2026 updates to appropriate filtering and monitoring provide greater clarity for schools and colleges on how to meet their statutory safeguarding responsibilities—particularly in response to evolving technologies, including mobile platforms and generative AI. 

Building on the 2025 definitions, the latest updates strengthen expectations around real-world effectiveness, transparency, and technical capability, helping schools better understand both what systems should do—and where their limitations lie. 

The 2026 filtering guidance introduces several key clarifications that strengthen compliance expectations: 

Non-bypassable protection for illegal content 
Schools must ensure that filtering systems apply blocklists (e.g. for child sexual abuse material and terrorist content) that cannot be disabled or altered by any user, including administrators 

Greater emphasis on real-time and contextual filtering 
Filtering systems should now be capable of analysing content dynamically, including user-generated and AI-generated content, rather than relying solely on URL or category-based blocking 

Improved transparency on technical limitations 
Providers are expected to clearly explain how filtering works on encrypted traffic and where technical limitations may affect effectiveness  

Expanded coverage of mobile devices and apps 
The guidance recognises that content is increasingly accessed through apps and cloud services, and schools should understand what filtering applies within apps—and where it may not 

These changes reinforce the expectation that filtering systems must be effective in modern, real-world environments, not only traditional web browsing contexts. 

The 2026 monitoring guidance complements these changes by strengthening expectations around how schools identify and respond to safeguarding risks: 

Clearer monitoring strategies linked to risk assessment 
Schools should select monitoring approaches (physical, logfile-based, or active/pro-active systems) based on their specific safeguarding risks and context 

Greater emphasis on capability and response 
Monitoring systems must be supported by: 
– Sufficient staff capacity 
– Appropriate safeguarding expertise 
– Processes to review, prioritise and act on alerts 

Improved expectations for mobile and app monitoring 
Schools should understand how monitoring applies across: 
– Mobile devices 
– Apps and embedded browsers 
– Remote use of school devices 

Stronger requirements for logging and identification 
Monitoring systems should be able to identify users and attribute activity, enabling timely intervention where concerns arise 

 These updates highlight that monitoring is not just about data collection, but about effective safeguarding response and intervention. 

The 2026 updates reinforce the distinction between the two core safeguarding technologies: 

Filtering: controls access to content and services 

Monitoring: observes and reports activity to support safeguarding intervention 

This clarification supports schools in ensuring both systems are implemented appropriately and work together as part of a broader safeguarding approach. 

Reflecting developments first introduced in 2025, the 2026 guidance further develops expectations around generative AI: 

– Filtering systems should prevent access to harmful AI-generated content 
– Monitoring systems should maintain robust logging of interactions with AI tools  

Schools are encouraged to: 

– Assess which AI tools are approved for use 
– Understand any technical limitations, such as whether your solution can monitor and filter real-time, dynamic, personalised or AI‑generated content 
– Develop clear policies governing AI use 

This reflects the growing importance of managing dynamic, user-generated content within education settings. 

While the core safeguarding duties remain unchanged, the 2026 updates place greater emphasis on: 

– Understanding how systems work in practice 
– Recognising technical limitations and risks 
– Ensuring effective monitoring and response capability 
– Extending safeguarding beyond the browser to apps, devices and AI tools 

Filtering and monitoring remain supporting tools, and must be complemented by:

 – Effective teaching and supervision 
– Regular risk assessment and review 
– Clear policies and staff training 

The 2026 updates represent a shift from “having systems in place” to demonstrating that those systems are: 

– Technically effective 
– Transparently understood 
– Properly managed 
– Fully integrated into wider safeguarding practice 

This ensures schools are better equipped to protect children in an increasingly complex digital environment.
